Let's take any edge length l. The diagonal has length

. In our case it's
Answer:
- D. They are similar by the definition of similarity in terms of a dilation.
Step-by-step explanation:
<em>Refer to attached</em>
The points are plotted and connected to make triangles
As per the diagram, the triangles are similar, each side of ABC is reduced twice to make the corresponding sides of DEF, so the scale factor is 1/2.
<u>Correct choice is D</u>
- They are similar by the definition of similarity in terms of a dilation.
Answer:
My guess is 195.
Step-by-step explanation:
225 + 120 = 345 - 150 = 195
Answer:
1/12t=1/3h
t=?
1/12t*12=t
t=(1/3h)*12
t=4h
filling the tank takes 4 hours.
The answer should be D. 10.
Substitute x for the number 3 in the first equation.
f(x)=2(3)+1, then solve to get x=7
Substitute 7 for x in the second equation
g(x)=(3(7)-1)/2
g=(21-1)/2
g=(20)/2
g=10
